Technology wise most of the important stuff more than 50 years ago. They did it without internets, lasers, and power tools. The first mechanical computer was built roughly 200bc (no small feat considering the intricate small clockwork is insane for that time). The first self propelled road vehicle came about in the mid 1700's. The first real moped came in the late 1860's. The automobile has changed very little in the last 100 years. Look at the works of Da Vinci or Tesla, some of their works are just now being used and some are still radical even today. We have made a few advances in the last 50 years or so. We have discovered bigger and more efficient ways to destroy each other, weapons technology is always advancing. We do have a wider range of energy options. One thing we have done a decent job of is advances in medicine and understanding illness and diseases. That said are many people than haven't experienced the benefits of these advances yet. We have yet to form sustainable modern civilizations. Sadly we have failed at the most important thing, human rights. Sure, things are somewhat better than they have been, at least in some places. But thats not nearly enough. It would be very premature to actually step back and think "Look how far we've come", expecially on a global scale. There is always hope for the future though! Expecially if we can learn from the past and not make the same mistakes again. This post is way to serious for this thread, but whatever i got carried away.
